1. A surgical instrument for surgically joining tissue, the surgical instrument comprising:
- an end effector having a first jaw member and a second jaw member, at least one of the first jaw member or the second jaw member being movable with respect to the other jaw member, the first jaw member having a knife channel with a widened portion adjacent a distal end thereof;
a sled disposed in mechanical cooperation with the first jaw member and including two wedge portions and a connecting member therebetween, the sled having a distal most position with respect to the first jaw member in which the connecting member is disposed proximal of the widened portion of the knife channel;
a beam assembly for pushing the sled towards a distal end of the first jaw member, the beam assembly including a knife; and

Abstract
A surgical instrument including a handle assembly, an elongated portion, an end effector, and a stop member is disclosed. The end effector is disposed adjacent a distal portion of the elongated portion and includes a first jaw member and a second jaw member. At least one jaw member is movable with respect to the other jaw member between spaced and approximated positions. The first jaw member includes an upper tissue-contacting surface and a lower shelf portion. The shelf portion includes a groove disposed therein. The stop member is disposed adjacent a distal portion of the first jaw member and is pivotable with respect to the first jaw member between a first position, a significant portion of the stop member being positioned external to the first jaw member, and a second position where a lower portion of the stop member being positioned at least partially within the groove.
